A team of “European planetary geologists and young scientists” is assembling a mineral library to help future astronauts identify rocks on other worlds. “The goal,” according to the European Space Agency, “is to create a database of all known rocks and minerals on the Moon, Mars and meteorites surfaces for easy identification.”

This collection, assembled in anticipation of discoveries made far from Earth, can then be used as a basis of forensic identification and formal comparison. We will know future worlds through anticipatory fragments we have collected here on Earth.

There, the chemical spectra of rocks are analyzed to help understand “the mineralogical and geological evolution of terrestrial planets.” This, again, prepares humans and their robotic intermediaries to encounter landscapes so alien they cannot be understood at first glance, yet similar enough to our home world we can still work out what they’re made of.

Each building was installed at its specific location in order to collaborate in watching a particular star, and—as revealed by any inconsistencies of measurement—to find evidence of the Earth’s “wobble.” This was part of the so-called “International Latitude Service.”

The building seen here basically operated like a machine, with a sliding-panel roof controlled by a rope and pulley, and a solid concrete foundation, isolated from the building itself, on which stood a high-power telescope.

This pillar gives the building a vaguely gyroscopic feel, or perhaps something more like the spindle of a hard drive: a central axis that grounds the building and allows it to perform its celestial mission.

What’s interesting, however, is that this absolutely heroic building program—a structure for measuring heavenly discrepancies and, thus, the wobble of the Earth—is hidden inside such an unremarkable, everyday appearance.

It’s a kind of normcore beach hut that wouldn’t be out of place on Cape Cod, with one eye fixed on the stars, a geodetic device revealing our planet’s wobbly imperfections, masquerading as vernacular architecture.

Last summer, I got obsessed with the idea of how future crimes will be investigated on Mars. If we accept the premise that humans will one day settle the Red Planet, then, it seems to me, we should be prepared to see the same old vices pop up all over again, from kidnapping and burglary to serial murder, even bank heists.

If there is a mining depot on Mars, in other words, then there will be someone plotting to rob it.

But who will have the jurisdictional power to investigate these crimes? What sorts of forensic tools will offworld police use to analyze Martian crime scenes contaminated by relentless solar exposure, where the planet’s low gravity will make blood spatter differently from stab wounds? Further, if there is a future Martian crime wave, what sort of prison architecture would be appropriate—if any—for detaining perpetrators on another world?

Over the long and often surreal process of researching these sorts of questions, I spoke with legendary sci-fi novelist Kim Stanley Robinson, with Arctic archaeologist Christyann Darwent, with space law expert Elsbeth Magilton, with astrobiologist and political activist Lucianne Walkowicz, with political theorists Charles Cockell and Philip Steinberg, and with UCLA astrophysicist David Paige. All of them, through their own particular fields of expertise, helped chip away at various aspects of the question of what non-terrestrial law enforcement.

Incredibly, I also met a 4th-degree black belt in Aikido named Josh Gold who has been working with a team of advisors to develop a new martial art for space, rethinking the basics of human movement for a world with low—or even, on a space station, no—gravity. How do you pin someone to the ground, for example, when is no ground to pin them on?

In any case, will we need a Mars P.D.? If so, what exactly might a Martian police department look like?

Anyway, there was an amazing story last week suggesting that, deep inside the planet, minerals might exhibit flaws associated with “collisions with dark matter.” In a sense, this would make the entire interior of the earth a de facto dark matter detector—or, according to researchers at the University of Michigan, “minerals such as halite (sodium chloride) and zabuyelite (lithium carbonate), can act as ready-made detectors.”

Proving this hypothesis sounds like the opening scene of a blockbuster science fiction film: “An experiment could extract the minerals—which can be around 500 million years old—from kilometres-deep boreholes that already exist for geological research and oil prospecting. Physicists would need to crack open the extracted minerals and scan the exposed surfaces under an electron or atomic force microscope for the tracks made by recoiling nuclei. They could also use X-ray or ultraviolet 3D scanners to study bigger chunks of minerals faster, but with lower resolution.”

Meanwhile, ScienceDaily reported earlier this month that flaws deliberately introduced into the crystal forms of diamonds could be structured such that they improve those diamonds’ capacity for quantum computation. Apparently, a team at Princeton has designed new kinds of diamonds “that contain defects capable of storing and transmitting quantum information for use in a future ‘quantum internet.’”

There is obviously no connection between these two stories, but that won’t stop me from imagining some vast new quantum computer network, coextensive with the Earth’s interior, performing prime-number calculations along dark matter-induced crystal flaws, crooked mineral veins flashing in the darkness with data, like some buried circuitboard throbbing beneath the continents and seas.

An interesting story that re-emerged during recent coverage of the Thai cave rescue is that a team of British cavers trapped underground in central Mexico for “more than a week” back in 2004 had been accused of having an ulterior motive.

The conspiracy seems to have begun when someone noticed a particular piece of equipment in a photo of the caving team: “someone spotted radon dosimeters being used. This wasn’t a military training exercise; it was a bunch of guys on holiday, some of whom happened to be in the armed services.”

What the British team would even have done with such materials, if they had found them, including how they would have safely transported uranium out of the underworld in their caving gear—not to mention how they would have exploited this knowledge later, perhaps by developing a vast, illegal, underground mine in the middle of central Mexico?—is difficult to imagine, but, wow, would I like to read that novella.

Six British soldiers descend into the Earth beneath Mexico looking for the infernal materials of war, part of a much larger, secret global mission for subterranean weapons-prospecting, slipping into caves in Central America, the U.S. Southwest, the Namibian desert, and beyond, combining raw international espionage, classified satellite reports, weaponized mineralogy, advanced underground mapping techniques, and every gear-head’s camping equipment fantasy turned up to 11.

“Radar satellite images show significant movement of the ground across a 4000-square-mile area—in one place as much as 40 inches over the past two-and-a-half years,” Phys.org reports. The land is tidal, surging and rolling with artificially induced deformation.

“This region of Texas has been punctured like a pin cushion with oil wells and injection wells since the 1940s and our findings associate that activity with ground movement,” one of the researchers explains.

What’s particularly fascinating about this is why it’s alleged to be happening in the first place: a jumbled, chaotic, quasi-architectural mess of boreholes, abandoned pipework, and other artificial pores has begun churning beneath the surface of things and causing slow-motion land collapse.

For example, “The rapid sinking is most likely caused by water leaking through abandoned wells into the Salado formation and dissolving salt layers, threatening possible ground collapse.” Or a nearby region “where significant subsidence from fresh water flowing through cracked well casings, corroded steel pipes and unplugged abandoned wells has been widely reported.”

This utterly weird, anthropocenic assemblage—or should I say anthroposcenic—has also changed the terrain in other ways. Water leaking into an underground salt formation has “created voids,” for example, which have “caused the ground to sink and water to rise from the subsurface, including creating Boehmer Lake, which didn’t exist before 2003.” It’s like upward-falling rain.

The site brings to mind the work of Lebbeus Woods: jammed-up subterranean infrastructure, in a sprawling knot of abandoned and semi-functional machinery, causing the solid earth to behave more like the sea.

It involves installing a gold-plated laser somewhere deep in the San Andreas Fault to extract geothermal energy from the landscape. Think of it as a kind of gonzo version of the San Andreas Fault Observatory at Depth.

The press release, from architect Mark Foster Gage, is a great example of a solipsistic inventor’s imagination at full blast—featuring “geothermal resonance technologies,” nano-gold foil-wrapped laser components, an “experimental phenolic cured resin foam,” and so on.

Or see Norway’s extraordinary Hessdalen lights, a geologically electrified valley that seems ripe for a Mark Foster Gage-like architectural-energy proposal.

In all these cases, of course, what’s also worth noting is that, as fantastic as this sort of facility might seem—whether it’s a lab extracting electrical energy from the San Andreas Fault, as Foster Gage suggests, or one positioned above geochemical differentials in the Canadian soil—as soon as the power it supplies can be made available through the national grid, it would immediately pass from some sort of absolutely bonkers sci-fi vision of the near-future to, frankly, something utterly mundane. It would simply be where the power comes from, and people would shrug it off as a mere utility (if they think about it at all).

But what this also means is that we might already, right now, be missing out on seeing the truly otherworldly nature of our own power-generation facilities, which have all too easily disappeared into the infrastructural background of the modern world. Science fiction is already here, in other words, we just tend to refer to it as infrastructure. See, for example, Crescent Dunes or PS10. Or, for that matter, take a harder look at oil.

In any case, here’s a sample from the project text, obligatory typos and all:

The exhibited technology capitalizes on the unique tungsten-saturated substrate of the San Andres fault through the use of a visible-light Q-switched Nd:YAG lasers, tuned to extract sustainable magno-electrical energy from a +678 degree Kelvin supercritical water deposits located adjacent to a stable magma chamber 4.4km beneath the Earths surface. This supercritical water, that behaves both as liquid and gas, is vaporized through 3,780 Kelvin bursts which at peak power induce a supercritical matter state releasing energy in exponential excess of its matter equivalent. The presence of heterogeneous frequency fields in metal deposits along the strike-slipping continental plates supercharges the pockets of supercritical water with magnetic nuons which are forced upwards with velocity µ as a result of the pressure gradient along the vertical faults. Due to the variable decay rate of metals in the presence of such high trajectory nuons, the prototype laser resonance mechanism itself is encased in an experimental phenolic cured resin foam (Cas no. 000050-00-0 with a normal specific gravity of 120 kg/m3) which insulates the process from outside magnetic interference. For rapid nuon decay protection the foam resin is additionally coated with the same seven µm micrometer nano-gold foil used to encase existing NASA satellites. This thick film of gold nano-molecules particles gives the machine its striking gold aesthetic appearance.

A nuon-resistant radiant machine buried in the San Andreas Fault, extracting energy from the friction between tectonic plates? With lasers? Yes, please.

I’ve long been a fan of generative landscapes—topographies created according to some sort of underlying algorithmic code—and I’m thus always happy to stumble upon new, visually striking examples.

Of course, geology itself is already “generative,” as entire continents are formed and evolve over hundreds of millions of years following deeper logics of melting, crystallization, erosion, tectonic drift, and thermal metamorphosis; so digital examples of this sort of thing are just repeating in miniature something that has long been underway at a much larger scale.

“All those years ago,” NPR reported earlier this week, “as potters continued to throw clay, the molten iron that was rotating deep below them tugged at tiny bits of magnetic minerals embedded in the potters’ clay. As the jars were heated in the kiln and then subsequently cooled, those minerals swiveled and froze into place like tiny compasses, responding to the direction and strength of the Earth’s magnetic field at that very moment.”

Archaeologist Erez Ben-Yosef, one of the researchers on the project, has compared the process to a terrestrial “tape recorder,” and a particularly sensitive one at that: the resulting jars “provide an unprecedented look at the planet’s magnetic field over those six centuries, one that’s much harder to get from rocks.”

These accidental indices also indicate that the Earth’s magnetic field at the time was much stronger than expected; ominously, this “astonishing geomagnetic spike,” as mentioned above, could happen again. Indeed, the jars have “given scientists a glimpse of how intense the magnetic field can get—and the news isn’t good for a world that depends on electrical grids and high-tech devices,” Annalee Newitz writes for Ars Technica.

“The researchers note that this geomagnetic spike is similar to another that occurred in the 10th century BCE,” Newitz adds. “Data from the 10th century spike and this 8th century one indicate that such events were probably localized, not global. That said, they write that ‘the exact geographic expanse of this phenomenon has yet to be investigated, and the fact that these are very short-lived features that can be easily missed suggests that there is much more to discover.’”

This vision—of highly localized, mysterious geomagnetic storms frying electronics from below—is not only a great plot device for some burgeoning scifi novelist, it could also almost undoubtedly be weaponized: subterranean geomagnetic warfare against an entire region of the planet, short-circuiting every electrical device in sight.

Of course, it’s also worth noting that this would still be happening: that is, today’s ceramics should still be “recording” the Earth’s magnetic field, even without any corresponding spike in that field’s strength. An invisible terrestrial forcefield is thus still inscribing itself inside objects in your kitchen cabinet or standing on your breakfast table. Everyday knick-knacks in retail stores around the world are still archives of planetary magnetism.

This also makes me wonder what other types of artifacts—clay figurines from nomadic Arctic tribes, mud bricks from central Africa—might also house geomagnetic records yet to be analyzed by modern technology. So what else might be discovered someday?

I’m reminded of the possibility that space weather—or “fossils of spacetime”—might be frozen into the built environment in the form of GPS glitches: hidden inside minute structural errors in large building projects, such as freeways, dams, and bridges, there might be evidence that our solar system is passing through “cosmic kinks” of dark matter.

Various teams of astronomers have been using “deep-learning neural networks” to generate realistic images of hypothetical stars and galaxies—but their work also implies that these same tools could work to model the surfaces of unknown planets. Alien geology as dreamed by machines.

The Square Kilometer Array in South Africa, for example, “will produce such vast amounts of data that its images will need to be compressed into low-noise but patchy data.” Compressing this data into readable imagery opens space for artificial intelligence to work: “Generative AI models will help to reconstruct and fill in blank parts of those data, producing the images of the sky that astronomers will examine.”

The results are thus not photographs, in other words; they are computer-generated models nonetheless considered scientifically valid for their potential insights into how regions of space are structured.

What interests me about this, though, is the fact that one of the scientists involved, Jeff Clune, uses these same algorithmic processes to generate believable imagery of terrestrial landscape features, such as volcanoes. These could then be used to model the topography of other planets, producing informed visual guesstimates of mountain ranges, ancient ocean basins, vast plains, valleys, even landscape features we might not yet have words to describe.

The notion that we would thus be seeing what AI thinks other worlds should look like—that, to view this in terms of art history, we are looking at the projective landscape paintings of machine intelligence—is a haunting one, as if discovering images of alien worlds in the daydreams of desktop computers.

Over at the consistently interesting Anthropocene Review, a group of geologists and urbanists have teamed up to calculate the total mass of all technical objects—from handheld gadgetry to agricultural equipment, from domesticated forests to architectural megastructures—produced by contemporary humanity.

Their seemingly impossible goal was to gauge “the scale and extent of the physical technosphere,” where they define the technosphere “as the summed material output of the contemporary human enterprise. It includes active urban, agricultural and marine components, used to sustain energy and material flow for current human life, and a growing residue layer, currently only in small part recycled back into the active component.”

The active technosphere is made up of buildings, roads, energy supply structures, all tools, machines and consumer goods that are currently in use or useable, together with farmlands and managed forests on land, the trawler scours and other excavations of the seafloor in the oceans, and so on. It is highly diverse in structure, with novel inanimate components including new minerals and materials, and a living part that includes crop plants and domesticated animals.

Their “preliminary” calculations of all this suggest a mass of 30 trillion tons.

The authors immediately put this number into a darkly awe-inspiring perspective:

If assessed on palaeontological criteria, technofossil diversity already exceeds known estimates of biological diversity as measured by richness, far exceeds recognized fossil diversity, and may exceed total biological diversity through Earth’s history. The rapid transformation of much of Earth’s surface mass into the technosphere and its myriad components underscores the novelty of the current planetary transformation.

This “rapid transformation of much of Earth’s surface mass into the technosphere” means that we are turning the planet into technical objects, dismantling and recombining matter on a planetary scale. The idea that the results of this ongoing experiment “may exceed total biological diversity through Earth’s history” is sobering, to say the least.
